'neronfv'nnrotn To all whom z'v' may concern.' y f '.f

Be it known that l, PAUL F. Kesnonnnrt,l a subject of the Emperor 'of Germany, residing at Stevens Point, in the countyl I" Portage and State of Wisconsin, have' in-V vented certain new and useful improvements in Motor-Vehicles; and l do declare the ioliotving to be a full, clear, end exact description of the invention, `such as will enable others skilled in the art to which 4it appertains to make and use'. the same. I

My invention has for its principal object to provide an improved means for, driving motor vehicles, consisting essentially 'of a diiierentisl, a plurality of "longitudinal drive shafts leading therefrom to theour Wheels or" the machine, and ineens for steeri hicle;

ing all of said Wheels simultaneously.

A'iurther object is to so locate the differ entiel es to permit all of said drive shafts to he of uniform length in order that the torsional strain thereon may beeequalized to equally distribute the driving power to all four Wheels. A

vYet another obiect is to so arrange the 'several parts of the device as to permit the iront and rear axles and their respective drive shafts to iioat freely.

With 'the foregoing general objects in view, the invention resides in certain novel features of construction and unique combi nations of 'parte to be hereinafter fully described and elainhed, the descriptive matter being supplemented by the accompanying drawings which constitute a part oi this applica-tion and in which:

Figure l is a top plan vien of the rnnning gear or chassis of the improved ve Fig. 2 is 4a view similar to Fig. l on an enlarged scale With parts broken sway and in section;

Fig. 3 is a transverse section on the plane of the line 3 3 of Fig. 2; t

Fig. 42 is a'detail vertical section on the plane of the line 4 4 of Fig. 3. Y

ln the drawings above brieiy described, the'nunierel l has reference to a horizontal chassis freine supported by springs 2 from front and rear axles 3, the ends of seidaxles carrying suitable Wheels 4 mounted in a manner to be described for horizontal turning. A differential 5 is mounted on the frame l at the longitudinal centi thereof and is driven by means of a sbat f'rom spammen einstimmen. ,Patentes Ngs-ginie pensants eigenaresse, nur., seriele. intese. f

my suitable type .of motor, said dierential toxfrontand rear pairs of longitudinally' 'serving -to 'transfer' power from said niotorv Y,

a slight siiding movement so as to permit', i.

`free oating of the two axles.

The housing 8 of the dierential isse-l cured in any suit'eble manner to the freiney l and carries appropriate bearings for .e

pair of transversely extending'alined shets.

Each shaft 9 carries a beveled pinion 13 and front and rear similar pinions Lieshwtherewith, said ,last named pinions being carried by longitudinally disposed shafts 15 rotatably mounted in suitable beefrings'in the sides of the housing 8. rlhe outer ends of theshafts 15 are connected by universal joints ,16 to the inner ends are connected to short extension drive shafts '85 the inner sides oi housings 19 into thainy 18, said'last named shafts passing through terior of the latter, said housings beingf mounted on vertical king bolts 20 'in forksv 2i on the ends of the axles 3 and having outwardly projecting spindles 22 upon' which the Wheels 4 are mounted. rhe

i8 es well as the bolts 20 preferably pass through the inner ends 'of the spindies-A shafts sie.

spindles withinbores 23 formed through the inner ends of the `housings 19, the outer ends of said housings being closed by suitable plates 24- in running contact with the hubsor the Wheels. f The hub of each Wheel is provided on its inner end with a beveled gear ring 25, all of said rings being received in the housings 19 with their teeth in mesh with drivin@` pinions 26 on the ends of the extension drive 'shafts 18.

The arrangement of arts so far described transmits power to the Vfour Wheels and permits of turning thereof to steer the machine, thispower being transmitted unifornily toV all of said Wheels since the cen trai locationo the diierential 5 permits
